What is IBM Micromedex?

For more than 45 years, Micromedex has been one of the largest online reference databases about drug information, toxicology, diseases, acute care and alternative medicine. Delivered through a web portal with IP recognition, the comprehensive resource provides healthcare professionals with clinical decision support for informed treatment decisions. Micromedex facilitates decision making in the areas of drug information, disease and condition management, toxicology and alternative medicine. It even addresses specific questions, such as IV compatibility.

Micromedex evidence-based information contains:  

  • Drug dosing and medication management for all FDA-approved medications and select drugs approved by EMA and Health Canada  
  • Detailed information about drug interactions and IV compatibility  
  • Treatment protocols and checklists for acute and chronic disease management  
  • Lab information to help choose appropriate tests and interpret results


  • Alternative medicine information on herbal and alternative therapies  
  • Neonatal and Pediatric drug information for age-and indication-specific considerations  
  • Detailed protocols for toxicology and exposure management

IBM Micromedex with Watson

Since the mid-1970s, Micromedex has been considered an industry standard for clinical decision support. Micromedex has been a pioneer in distributing medical and clinical drug information, whether through microfiche, CD-ROMs, standalone PCs, mainframes, intranets or the internet.

Micromedex’s most recent iteration, IBM Micromedex with Watson combines the artificial intelligence (AI) of IBM Watson with the evidence-based clinical decision support of IBM Micromedex. It can help accelerate access to information by bypassing the keyword-based search process in favor of a search box that accepts natural language queries.

IBM Micromedex with Watson can answer drug reference questions from specific content within Micromedex, including:

  • Quick answers for drug classes
  • FDA-approved and off-label indications
  • Dosing and administration
  • IV compatibility
  • Medication safety
  • Mechanism of action
  • Pharmacokinetics and drug interactions

Why Micromedex is important

Micromedex is used to help support safe and effective drug therapy decisions at the point of care. Micromedex can also:

  • Help reduce medication errors and improve patient outcomes
  • Provide evidence ratings and recommendations, supporting clinical decision-making
  • Guide off-label use decisions supported by complete, cited evidence
  • Support Patient Safety initiatives and Joint Commission compliance

The Micromedex NICE-accredited editorial processes ensure quality and consistency. Professional editorial staff continually evaluate the world’s biomedical literature and regulatory actions, ensuring that Micromedex contains the most clinically accurate, relevant, and consistent drug reference information available.


Beyond drug summaries and package insert data to deliver full evidence

Micromedex provides in-depth coverage of on- and off-label drug use, mechanism of action and pharmacokinetics, adverse drug effects, relevant clinical trial results, therapeutic use and comparative data.

Evidence and efficacy ratings

Strength of evidence and efficacy ratings help guide clinical decision-making, whether evaluating a more common drug therapy option or drug therapy options for a rare disease or condition.


Access anytime, anywhere

Micromedex mobile apps are available for Apple iPod Touch, iPhone and iPad and Android® phones and tablets.
